-
, (2008/06/13)
A method of inhibiting angiogenesis in a warm blooded animal which comprises administering to said animal an anti-angiogenic effective amount of a compound of the formula: STR1 wherein the dotted line between positions C-1 and C-2 means the presence or absence of a double bond; the ?bond at C-6 denotes α or β; wherein R1 is CH3 or --C2 H5 ; wherein R2 is H, and R3 is in the α-position and is --OH, --O-alkyl(C1 -C12), --OC(=O)alkyl(C1 -C12), --OC(=O)aryl, --OC(=O)N(R)2, or --OC(=O)OR7, wherein aryl is furyl, thienyl, pyrrolyl, or pyridyl wherein each of said hetero moiety is optionally substituted with one or two (C1 -C4)-alkyl groups or aryl is --(CH2)f -phenyl wherein f is 0 to 2 and wherein the phenyl ring is optionally substituted with one to three groups selected from chlorine, fluorine, bromine, alkyl(C1 -C3), alkoxy(C1 -C3), thioalkoxy(C1 -C3), Cl3 C--, F3 C--, --NH2 and --NHCOCH3 and wherein R is hydrogen, alkyl(C1 -C4), or phenyl and each R can be the same or different; and wherein R7 is aryl as herein defined or alkyl(C1 -C12); or wherein R2 is α-Cl and R3 is β-Cl; or wherein R2 and R3 taken together are oxygen (--O--) bridging positions C-9 and C-11; or wherein R2 and R3 taken together form a double bond between positions C-9 and C-11; wherein R4 is H, CH3, Cl or F; wherein R5 is H, OH, F, Cl, Br, CH3, phenyl, vinyl or allyl; wherein R6 is H or CH3 ; wherein R9 is H, OH, CH3 F or =CH2 ; and wherein R10 is H, OH, CH3 or R10 forms a second bond between positions C-16 and C-17.
